Orbital exenteration in elderly patients: personal experience.
Orbital exenteration is a disfiguring procedure which typically involves removal of the entire contents of the orbit including the periorbita, appendages, eyelids and, sometimes, a varying amount of surrounding skin. This operation is reserved for the treatment of potentially life-threatening malignancies arising from the orbit, paranasal sinuses or periocular skin. The marked increase in the average life span and resulting greater incidence of invasive malignant skin tumours of the face, typical of old age, is the reason for the increased rate of exenterations in elderly patients. The purpose of this report is to describe personal experience regarding 8 operations of orbital exenteration carried out on elderly patients, 6 males and 2 females, age range 66-85 years (mean 75), who came to our observation, from January 2002 to December 2007, on account of cancer (7 cases: 4 basal cell carcinomas; 1 squamous cell carcinoma; 1 fibrosarcoma; 1 melanoma) or infectious inflammatory disease (1 case of rhinocerebral mucormycosis) and were treated with type III orbital exenteration (2 cases) and type IV orbital exenteration (6 cases according to Meyer and Zaoli's classification). The methods used to reconstruct the eye-socket consisted of a full-thickness skin graft in 5 cases, pedicled myocutaneous flaps in 2 cases--a latissimus dorsi muscle flap alone, in one patient, and combined with a pectoralis major muscle flap in another - and a combined lateral-based frontal fasciocutaneous pedicled flap and full-thickness skin graft in the oldest patient. Regarding survival and the local clinical situation, 3 of the 4 patients with basal cell carcinomas are alive and disease-free after 6 years, 2 years and 20 months, respectively, while the oldest patient died of the disease after 10 months. The subject who underwent surgery for squamous cell carcinoma is alive and disease-free after 2 years. The patients with melanoma, fibrosarcoma and mucormycosis died. Although there are various options available for reconstruction, full-thickness skin graft or a pedicled muscolocutaneous flap provide the simplest solution in the elderly population with significant co-morbidities. The final outcome is, in our experience, comparable to that of more complex flap reconstruction, obtaining very good final results with minimal donor site morbility and a reduced operation time.
